e flnsa a W eel 42 t rv xsaidishafti engaged at intervals and rotated by the Geneva pin l3 carried by the disc l on the drive shaft [4 which is driven by power obtained from any suitable source not shown. Since all of the forms and the mechanisms carried thereby are substantially identical, a description of one will sufiice for all. i p r While the form is in the horizontal position shown at the left of Fig. 1 and stationary, suitable turning mechanism removes the glove l6, which is in inside out position on the turning form ll (Fig. 5), from said turning form and mounts it in right side out position on the heating form It. The turning mechanism consists of the jaws I8, I9 which grip'the wrist'of the glove between them at the proper time'and move horizontally toward the right to mount the glove on the form 10. as shown by the dash-dot lines indicating the positions of the grippers at the beginning and at the end of the strokes thereof. The operating mechanism for the grippers being fully disclosed in said Patent No. 2,286,059, ref erence is made thereto for the full description thereof. After the glove has been fully turned and mounted on the heating form, the palm clamps are moved toward the palm and clamp the glove tightly against the form. The thumb straightener 2| is simultaneously moved in the same direction to start the straightening of the thumb and is also moved outwardly of the form and also transversely toward the center of the form to stroke the thumb into its proper folded position against'the palm. At the same time, the rods 22, 23, 24 and 25, slidably mounted within the form, are moved outwardly to tension the finger tips of the glove and to move them a sufficient distance longitudinally and away from the palm clamp 20 to stretch the glove to the desired extent and thereby to press it (Fig. 5), the glove being maintained in its stretched and clamped position and meanwhile being heated until it reaches the stripping position shown at the'lowermost part of Fig. 1. a

As best seen in Fig. 1, in which the usual cover plate for the form In has been omitted to expose the parts which otherwise would not be seen, a heating plate 26 is arranged in the interior of the form and is heated by a suitable heating element which also heats the form, said element being electrically connected to a suitable source of current by the wires 21, 28 passing through'the form and the hub branch 23 on which the form is mounted. The wires also pass through-the shaft H and are connected-to a suitable commutator not shown'such as is disclosed for example in Patent No. 2,148,403, the wires rotating with the shaft, hub branch and form as a unit.

The hub branch supports 23 for'carrying the forms are each made hollow to receive the inner end portions 30 of the form, and each branches radially from the sleeve 3! (Fig. 3) which is integral therewith and which is secured to the shaft II for rotation therewith; To removably clamp the form to the branch, each branch is split longitudinally along one side thereof and the split parts are tightened about-the end 30 of the form against the shoulder 'and at its right end against the washer-'36 fixed to the rod whereby the rod is urged toward therlghtby the spring. 1 75 At its left end, the main rod 33 carries'the cross 4 bar 31 on which are mounted the stretching rods 22, 23, 24 and 25 sliding respectively in the fingers 38, 39, 4B and 4| of the form. As shown in Fig. 1, the entire tip of each form finger is secured to one of the corresponding stretching rods, whereby movement of the main rod 33 moves the finger tips 42, 43, 44 and 45 outwardly to the dash-dot position thereof indicated.-

It will be understood however, that the finger tips may be made integral with the remainders of the form fingers respectively and drilled to .permit sliding of the stretching rods therethrough. This form or the invention is shown in, Fig. 6, wherein the rods 46, 41, 48 and 49 slide withinandare extensible beyond the fixed tips of the form 50 to perform the stretching opera- 1 tion, but when the rods are retracted, the outer ends thereof are flush with the fixed tips. This structure is advantageous where the glove is of such material and size as to be likely to Stick or adhere so comparatively tightly to the form as to resist normal stripping of the stretched glove therefrom, in which case the full size finger tips as 42 may not at the proper time be freed of the finger tips of th glove.

part such as the frame 53 of the machine (Fig. 3). The cam roller 54 operated by the cam 5| is piv oted as at 55 to the supportmember 55 which is secured to the main rod as at 51. As the shaft H begins its rotation to carrythe forms out of I the positions thereof shown in Fig. 1, the roller 54 rides up on the cam and moves toward the left as viewed in Figs. 1, 2 and '3, thereby moving the j support member 58, the main rod 33, the bar 31, the stretching rods and the finger tips in the same direction to extend said tips and to stretch the glove, which has previously been clamped to the form by the palm clamps. Said palm clamps are not moved longitudinally, but are oscillated toward and away from the palm. One of the clamps is provided on each side of the form In, both clamps being operated 7 in unison. Each of the palm clamps 23 is prefer'ably knurled on'its inner surface to grip the glove material firmly, one of the palm clamps 20 being secured as at 6| to the lever 62 which is pivoted to the hub branch 29 as at 63 (Figs. 2 and 3) the other clamp 20 being secured as at Bl to the lever 62' pivoted at 63'. To operate the levers i other arm carries a third roller 68, said rollers" 61 and 68 being at about the same distance on each side of the pivot 65. The cam roller 66 is operated by the bevelled end 69 of the'fixed cam 10 at the proper time to rotate the lever 64 in a clockwise direction as viewed in Fig. 3, said cam 10 being suitably secured to the fixed cam i 5!. On such rotation of the lever 64, the roller '61 thereon rides up on the bevelledcam l l secured tothe lever 62 and theieorresponding roller 68 V rides up on the'similar bevelled cam I2 fixed to the other lever 52', thereby moving the levers 62 and 62' toward'each other and toward the form to clamp the glove between the clamps 2n and V the form. To urge said levers toward their nor mal positions in lateral spaced relation to the form, the compression spring 13 is mounted between said levers on the pins 14 projecting therefrom.

tates it i be understood ages thumb platesgii;

both of the members beingsilitably securedltothei m tained through the cam projection 8| on each member 15 (Fig. 2). Said projection is engaged by the relatively fixed roller 82 on the lever 62 or 62' as the members are extended thereby causing the roller to ride up on the high part of the projection and swinging said members 15 toward the center line of the palm about the pivots TI and against the action of the springs 83, one of which is secured to the lever 62 and the other to the lever 62' and which urge the members 15 outwardly or away from the center line of the palm. Such movement of the members 15 and the plates 2| carried thereby straightens the glove thumb and folds it inwardly toward the center of the palm, regardless of whether the glove is a right hand glove or a left hand one.

To clamp the thumb against the palm, the member 15 passes through and slides in the groove 84 between the outstanding lug 85 at the left end of each of the levers 62 and 62' and the plate 20 adjacent thereto, whereby movement of said lever about its pivot also swings the member 75 and the support lever 16 therefor about its pivot 79 or 80 during the longitudinal movement and transverse movement of said member into the position shown in Fig. 5.

It will be noted that the clamping, stretching and thumb straightening operations begin as the form is rotated out of the glove mounting position thereof and that the glove remains stretched and heated for about three quarters of a, revolution of the shaft ll, whereafter the cams i and become effective to permit the rollers to ride off the high parts thereof. The various springs above described then become operative to restore the clamping, stretching and thumb straightening parts to the initial inoperative positions thereof ready for the repetition of the operations on the next glove to be mounted on the form. When the tips 42, 43, 44 and 45 or the rods 46, 41, 48 and 49 are retracted, the stretched and set finger tips of the glove nevertheless overhang the finger tip end of the form and the thus loosened finger tips are easily gripped or operated upon by suitable stripping mechanism to strip the glove off the form at the station just prior to the glove mounting station, the glove and the thumb thereof being released from the clamping mechanism at the stripping station.

It will further be noted that while the stripping mechanism, such as is shown in the prior patents above referred to, may be efiective to perform a final pressing operation upon the glove, the larger part if not all of the pressing, that is, free- 6! ing the: 'glovegofiwrinklesl and shaping it to .its; required substantially fiat form, is accomplished by the comparatively prolonged stretching of the glove while it is heated, so that the final pressing operation may in most cases be dispensed with t desi ed- 'It will also be seen that I have-provided means,-
